When it is required to find the area of a rectangle using classes, object oriented method is used. Here, a class is defined, attributes are defined. Functions are defined within the class that perform certain operations. An instance of the class is created, and the functions are used to find ... Read More

When it is required to sum the number of digits in a list, a simple loop and the ‘str’ method can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).The ‘str’ method converts the given ... Read More

When it is required to remove empty tuples from a list of tuples, a simple loop can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).A list of tuple basically contains tuples enclosed in a ... Read More

When it is required to sort the values of the first list with the help of the second list, the ‘sorted’ method and the ‘zip’ methods are used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).The ... Read More

When it is required to edit the objects inside a tuple, simple indexing can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on).Below is a demonstration for the same −Example Live Demomy_tuple = (45, 67, [35, ...

When it is required to display the letters common to two strings, the ‘set’ method can be used.Python comes with a datatype known as ‘set’. This ‘set’ contains elements that are unique only.The set is useful in performing operations such as intersection, difference, union and symmetric difference.Below is a demonstration ... Read More

When it is required to find longest common substring using dynamic programming with bottom-up approach, a method can be defined, that computes the solution to smaller problems. These smaller problem results don’t need to be computed again and again. Instead, they can just be accessed when required. This would lead ... Read More

When it is required to assign a specific value to the non max-min elements in a tuple, the ‘max’ method, the ‘min’ method, the ‘tuple’ method and a loop can be used.The ‘max’ method returns the maximum value among all of the elements in an iterable. The ‘min’ method returns ... Read More

When it is required to sort a list of tuples based on the second item, the lambda function and ‘sorted’ method can be used.A list can be used to store heterogeneous values (i.e data of any data type like integer, floating point, strings, and so on). A list of tuple ... Read More

When it is required to print an identity matrix, nested loops can be used.Below is a demonstration for the same −Example Live Demon = 4 print("The value of n has been initialized to " +str(n)) for i in range(0, n):    for j in range(0, n):       if(i==j):   ... Read More
